Dan Heller is President of Z-Code Software Corp., makers of electronic messaging software for UNIX, Mac, and PC/Windows platforms. His history with the X Window System dates back to 1987, when he developed some of the first toolkits to use Xt. In 1990, he developed Z-Code's first product, Z-Mail, using the Motif toolkit, concurrent with the writing of the first edition of the Motif Programming Manual, Volume 6A. Dan has a degree in Computer and Information Sciences from the University of California, Santa Cruz, and has since developed and brought to market many applications that integrate various well-known user interface styles from SunView to Motif to Open Look. Dan is also the author of O'Reilly & Associates' XView Programming Manual. Paula Ferguson is a writer for O'Reilly & Associates. In addition to co-authoring this book, she has written articles for The X Resource, helped update other volumes in the X series, and authored Volume 6B, Motif Reference Manual.

Paula graduated from the Massachusetts Institute of Technology in 1990 with a B.S. in Computer Science and Engineering.

When she can escape, Paula likes to go rock climbing, cycling, hiking, backpacking, and mountaineering.
